MINE CAR. m

Application led December 2S, 1926. Serial No. 157,550.

This invention relates to cars, and more particularly to cars of the type used in coal mines and industrial p ants.

rlhe invention has to do with cars of the type disclosed in the patent to Edmunds,

1,525,072, granted Feb. 3, 1925., u

The principal object of the inventlon 1s to provide a car provided with a body frame o1e rugged and durable construction, the

l@ parts of which may be manufactured and v assembled at reasonable cost, and when assembled provide a car ol greater load eapacity than the average car of substantially the same overall dimensions and weight.

l5 lThe invention has to do particularly with the construction of the body and its base trame, which rests upon a truck unit of the type disclosed in the above-ment1oned patent. l f

2@ Other novel features of the invention relate to the' bumper construction and the wheel mounting. y l

As will be understood by one skilled in the art, cars ol this character are used 1n mines where lthe rooms and entries are low and narrow; consequently, it is necessary that the dimensions of the car be kept within certain recognized limits, and that any increase in the capacity must be obtained so by a lowering of the center of gravity and an enlargement of the carrying space wlthin these limits. Furthermore, since cars of this type are subjected to rough usage, and severe strains, it is necessary that all the parts be securely united so as to form a substantially integral structure.

In the accompanying drawings, there `1s shown a preferred embodiment of the invention, in which:

Figure 1 is a side elevationalview.

Figure 2 is a bottom plan.

Figure 3 is a longitudinal section on the line 3-3 of Figure 2.

re d is a transverse section on the line @-4 of Figure 2, looking in the direction of the arrows.

Figure 5 is a transverse section on the line 5 5 of Figure 2. i

' Figure 6 is a perspective of the body base 5o frame mounted upon the truck.

Fi re 7 is a fragmentary sectional view' showing the wheel mounting.

'Referring to thedrawings for a more detailed description, T indicates thel truck which comprises a pair of sill castings at each side, each pair of castings having the wheels therebetween mounted. on stub axles supported by the castings. ln the drawings 10, 11. indicate the inner castings, and 12,

- 13 the'outer castings of each pair. The two pairs` of castings are united by suitable cross girts such as the end cross girts 14, 15 extending between the inner `castings 10, 11 and secured to inwardly extendin lugs 16, thereon. A central cross girt 1% extends through the inner castings 10, 11 to which itis connected at 17, to the outer castings, and is secured at 18 to inwardly extending lugs 19 on the outer castings. This truck unit is supported by means ofthe wheels 20, which are mounted upon stub axles 21, having suitable bearings 22 in the castings.

The axles are free to rotate or creep inv their bearings 22 and although they will not rotate with the wheels the axles will intermittently or slowly rotate, thus maintaining the lubricant therein in a fluid state and continuously fed to the wheel bearings.

lEach axle is'hollow, being provided with a lubricant entry port 24, and is held in position as by means of a Cotter pin 25 extending. through a protecting hood 26 extending outwardly from the axle'bearings in the outer casting.

When it is necessary to drop one of theV wheels, the `cotter pin may be withdrawn and the axle pulled outwardly through the wheel by means of a suitable axle puller,v

the end of which may be threaded into the vthreaded socket 27.

The truck above described, which, in construction, 1s similar to that illustrated in the.

patent mentioned, with the exception of the wheel mounting, is adapted to receive the body B which has a base frame, illustrated most clearly in Figure 6. The body base frame comprises pairs ol angle bars arranged at opposite sides, the members of eac-h pair of angle bars being suitablyco'iinected together; and the two pairs may also be connected by means of end crossvmembers.

Referringto the Figures 4, 5 and 6, the inner angle bar 29 of each pair instead of ein consists of a longitudinally extending center or web plate 30` having inwardly extending horizontal flanges 31. These flanges are .formed by providing angle members which o integrally fabricated formation,l

have vertical flanges 31 adapted to receive securing means, such las rivets 32, for securing the same to the wb 30.

It will be observed that the inwardly extending flanges 31 of the inner angle bars are not continuous, since they are arranged in substantially the lsame horizontal plane with the truck cross girts 14, 15, 17 to assist the latter in supporting the car floor. Between the cross girts, instead of providing flanges 31 on the body base frame, the sill bars or castings of the truck are formed integrally with inwardl extending webs or platforms 33 arrangedy in substantially the same horizontal plane of the cross girts and flanges 31 of the body base frame; thus the floor is provided substantially throughout its length between the base frame bars 29 with practically a continuous support. The inner bars of the base frame cooperate with outer bars 34 in the form of angle irons,

' which have inwardly disposed horizontal flanges 35 resting upon the top surfaces of the outer truck castings 12, 13. The flanges 35' serve to support the base frame on the truck and may be assisted by securing the central web 30 of the inner bars 29 to the inner truck castings, as by rivets or bolts 37. As will be observed, the inner base frame sill bars also have outwardly extending horizon` tal flanges 30,which may be either continuous so as to rest upon the inner truck cast'- ings, or, as illustrated in the drawings, cut away over the top surface of the inner truck castmgs for a purpose later to be described.

The outwardly extending horizontal flanges 30 are in substantially the same plane with the top surface of the inner truck castings 10, 11, and areformed by securing the vertical flanges 38 (Fig. 1) of suitable angle irons to the web 30. It will be understood that instead of forming the inner base frame bars 29 of separate elements, as illustrated in the drawings, these bars may be of one-piece construction, which at their ends, are of substantially Z-shaped cross-sectional formation, due to the provision of the inwardly extending floor supportin flanges 31 and the outwardly extending anges 30 thereabove.

At their ends, the members of each pair of base frame bars are connected by short angle members 39 (Fig. 6) riveted to the horizontal flanges 35 of the outer bars.` The twopairs may be joined at their ends by suitable cross members. In the present instance, at one end of the base frame, a cross strip v40 extends between .the outer angles 34 and is riveted to the depending vertical flanges 39 of the angle members 39. It is also joined by means of angle Ibrackets 41 to the webs 30 of the inner base frame bars29.

At'the opposite end of the base fra-me, the pairs ofy bars may be joined by'a plate 42 secured tothe depending flanges 39 of the angle brackets 39 at its lower end, and ex- 65 tended upwardly to form the end wall of the car (Fig. 4). Angle brackets 41', similar vin construction to the angles 41 securing the cross member 40 in position, serve to unite the end bracing wall 42 to the base frame. 70

It will be understood thatvthe end wall 42, constituting as it does a bracing element for the body base frame, as well as a portion of the body wall, effects a very secure union between the base frame and the super-posed body structure. It is joined along its side edges by means of interior angle brackets 43, with .the side walls 44, which, at their lower edges, lit within the vertical flanges 34 of the outer base vframe angles v34. The op- 90 posite end of the car is closed by a vertically swinging gate 46, the lower edge of which is positioned abovethe end cross member 40 of the base frame.

The bottom of the body may be formed by a central floor plate 47, carried by the inwardly extending flanges. 31 of the base frame by the cross girts of the truck and by the inwardly extending platforms 33 on the truck sill castings. It will be understood,

ofcourse, that although the loor is positioned above these elements, it may be carried below the same. The spaces betweenthe members of each pair of base frame angle bars may be closed by wheel hoods 48 having 95 base flanges 49 which rest directly upon the inner truck sill castings 10, 11 (Fig. 5), and upon the inwardly extending horizontal flanges 35 of the outer base frame angle bars.

It is for the purpose of maintaining the wheel hoods in substantially horizontal position and to bring the top surface of the higher truck sill castings 10, 1 1 in alignment) with the supporting flanges of the outer base frame angle bars (Fig. 4) that the outwardly 105 to rest directly upon t e inner truck sill cast- 5 ings. The spaces `between theV pairs of base frame angles at opposite sides of the hoods, maybe filled by suitable floor plates 50, resting upon and secured to the horizontal flanges 35, 30', of thebase frame side or an le bars.

t each end, the carlmay'be provided with a'bumper which is in the form .of a hollow steel casting, having a curved' outer depending flange 51 ,and a straight back vertically 1 2 depending flange 52, The two vflanges are connected by a top horizontal web 53 and vertical reinforcing webs or ribs 54 spanning the space between the flanges 51 and 52. The top surface of each bumper is socketed to receive the base 55 of a coupling tongue 56 and bolts 57 pass through the base of the tongue into the top web 53 of the bumper. The tongue and bumper being separately cast, may be readily separated should it be necessary to replace the coupling tongue because of breakage. This construction renders it unnecessary to discard the entire bumper should the coupling tongue break, and is a substantial improvement upon constructions heretofore employed in which the tongue is cast integrally with the bumper. Moreover, it has substantially the strength of an integral construction, due to the seating of the base 55 of the tongue in the socket on the top surface of the bumper; the strain of the pull does not tend to rock the tongue about its anchorage to the same extent as if the latter were simply secured to an unsocketed top surface of the bumper.

As will be understood, the construction as illustrated and described may be varied considerably without departing from the invention which is defined in the following claims.
